If you want to plant a peach seed in hopes of growing a peach tree, a little planting preparation will make it much more likely that your seed will germinate. However, the peaches you grow may not taste like the peaches your seeds came from. Commercial peach trees are usually grown in areas where there is established rootstock which can affect both flavor and texture.
Remove the pit from the peach. Run tap water over it and pull off all of the flesh, using a scrub brush if necessary. Lay the pit on a paper towel to dry. Once it's completely dry, place the pit in a resealable plastic bag, leaving the zipper open ½ inch. Put the bag in the refrigerator until December.
Fill a bowl with lukewarm water and immerse the pit for three hours. Fill the plastic bag with potting soil and place the pit inside, making sure it is completely covered. Watch for the seed to germinate, which will take between 30 and 45 days.
Dig a 4-inch deep hole in an area of your yard that has northern exposure and good drainage. Make this hole 1 inch wider than the width of the pit.
Place the pit in the hole and cover it with a loose layer of dirt. Make sure you cover any roots that have developed during the germination stage.
Put a 1-inch layer of straw or mulch on top of the hole to keep moisture in. Check the soil every day and water when it is no longer moist. Do not overwater; water should never puddle on top of the soil.
